ADJUSTABLE MOLD-JACKET.

Specification of Letters Patent.

Patented May 12, 1914.

To all whom it may concern:

Be it known that 1, JOHN L. NUTE, a citizen of the United States,residing at Shippensburg, in the county of Cumberland and State ofPennsylvania, have invented a new and useful Adjustable Mold-Jacket, ofwhich the following is a specification.

The present invention relates to improve ments in adjustable moldjackets, one object of the invention being the provision of a detachableand adjustable sectional mold jacket, adapted to be placed about thesand after the removal of the flask therefrom, and which can be readilyaccommodated to various sizes and shapes, the sections thereof beingprovided with a novel form joining means, which maintains the sectionsin the necessary position and so that the jacket may be readily movedinto and out of place.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the com bination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings-Figure 1 is a top plan View of the complete jacketassembled. Fig. 2 is a side elevation thereof, dotted lines illustratinganother position that the opposite side walls are capable of assuming.Fig. 3 is a side elevation taken at right angles to that shown in Fig.2. Fig. 4 is an enlarged detail plan View showing the method of securingthe abutting ends of two sections together.

Referring to the drawings, the numerals 1 and 2 designate the femalemembers or sections of the present jacket, while the numerals 3 and 4tdesignate the two male members or sections.

Each female member, as clearly shown in Fig. 8, is provided adjacent itsends with a. plurality of inclined slots 5, in the present instance twobeing shown, and with a plurality of vertical slots 6, there being twoshown in this instance. These slots in reality form a mortise for thereception of the tenons 7 formed upon the opposite ends of each malemember 3 or 4, said tenons being so constructed and shaped as to bereadily inserted through one of the mortises or slots 5 or 6 to assumeeither a vertical position, as clearly shown in Fig. 3, where the pins10 and 11 are disposed to enter any one of the various apertures 8 and 9of the tenons 7 to thus lock the female members relatively against andto the male members of the jacket.

l Vhcn the female members assume the dotted position shown in Fig. 2,the pins are adapted to be disposed upon both sides of the said memberso as to maintain it in a vertical position.

It will thus be seen that with this form of jacket, that the same whenpositioned, as shown in Figs. 1 and 2, constitutes a support for thesand which in reality is a frusto-pyramidal member while when in theposition as shown in Figs. 3 and 4, the male members are disposed in aperpendicular position with the female members either in an inclined orperpendicular position according to the positioning of the pins 10 and11. By this means it will be seen, that the sections or members may besecured in place for a specific or desired shape of mold, and that thesame may be readily slipped on or off of the mold to maintain the samein the desired position after the removal of the flask therefrom.

l/Vhat is claimed is:

1. An adjustable mold jacket, comprising four strips, two of said stripsadjacent the ends thereof being provided with mortises and constitutingthe female members of the jacket, and the remaining two strips beingprovided upon their ends with tenons for insertion in the mortises, andcooperating means detachably carried by the tenons and for abutment withthe adjacent portion of the female members for locking the members inadjusted position, the mortises of the female members being disposed atvarying angles relatively to each other, whereby the members whenassembled will form a rectangular )r a frusto-pyramidal jacket.

2. An adjustable mold jacket, comprising four strips, two of said stripsadjacent the ends thereof being provided with mortises and constitutingthe female members of the jacket, and the remaining two strips beingprovided with tenons for insertion in the mortises, the tenons of themale members being provided with two rows of apertures therethrough,pins insertible through the apertures and for abutting the adjacentportions of the female members for maintaining the mortise and tenonjoints as my own, I have hereto affixed my signalocked, the mortlses ofthe female members ture 1n the presence of two wltnesses. belng disposedat varylng angles relatively to each other, whereby the members whenJOHN LIVINGSTON NUTE' 5 assembled will form a rectangular or afruslVitnesses:
